A. CORPORATION OF NEW YORK LEAF rnrrrnn Application filed October 13,'1928. .Serial No. 312,240.-

This invention relates to a new and improved leaf flipper for use withloose leaf binders and is particularly well adapted to be used withloose leaf bindersof the split ring or arcuate prong type.

When binders of this type are open and it is desired to close them bymoving the covers towards each other such movement of the covers willmove the sheets. in thebinder around the binder rings or prongs. Thesheets of such binder are held in position by virtue of the fact thatthey are provided the outside edges the binder the outer edges of thesheets will be raised above the inner edges of'the sheetswith the resultthat the rings or prongs will assume an oblique position with'referenceto the apertures in the sheets which will cause the sheets to bind onthe rings or prongs to r a certain degree and resist movement aroundsuch rings orprongs. The sheets usually used with this type of binderbeing thin there is considerable possibility of injury to the sheetswhen they are thus forced along the rings. or

. sheets which are adjacent to the covers.

. In order -to permit'the movement of the sheets along thefirings orprongs it is desirable to provide a means which will provide a supportfor the leaves during such movement and which will also hold-the leavesin such a position with reference to the rings or prongs that there willbe no tendency of the leaves to bind on the prongs during theirmovement, and the main object of my invention is to provide a devicewhich may beinterposed between the leaves of a binder and the covers ofthe binder to act as a support and guiding means for the leaves whilethe binder is being closed. Other objects and advantagesrelate to thesize, shape and arrangement of parts all as will more fully appear fromthe following description taken in connection'with the ac companyingdrawings, in which'z' Figure 1 is a perspective view of theprcferredform of my device.

. For the purpose of explaining the construcprising a back member 2 andcovers 3 and 4 connected to'back member 2 by flexible hinges 5 and 6respectively; A curved spring plate 7 is afii'xed to the upper surfaceof back' member 2 by rivets or otherconvenientuneans, not

shown. Spring plate 7 has its opposite prongs, which is particularlytrue of thelongitudinal edges return'bent to form channels 8 and 9'. Atoggle plate 10 having aflixed ."tion and operation of my device I'havehere shown one type of.a split ring binder 1 com- 30 thereto aplurality, in this case shown as five, '4

of half rings 11 is positioned on back member 2 with one longitudinaledge in channel 9 of. spring plate 7. A second toggle plate 12 havingaflixed thereto a plurality, inthis case shown as larly positioned onback member 2 with its outer longitudinal edge in channel 8 of springplate 7. A plurality of double headed buttons 14, one only being shown,arepositioned between the inner longitudinal edges of toggle plates 10and 12 with such edges bje-- five, of half rings 13 is simitween theheads of the buttons 14. The com- ,bined width toggle plates" 10 and 12is slightly greater than the distance between channels 8 and 9 of springplate 7 so that when the inner longitudinal edges of toggle plates 10and 12 are below the outer longitudinal edges of such plates, in whichposition the upper end of half rings 11 and 13 are in contact, the partswill be held in this position by the pres- 10 sure of spring plate 7.When it is desired to raise the inner longitudinal edges of toggleplates 10 and 12 above the outer longitudinal edges of such plates toseparate half rings 11 and 13 suchmovement is permitted by theresiliency of spring plate 7, and when such movement has been completedthe parts will be yieldingly held in that position by the pressure ofspring plate 7 The movement downwardly of the inner longitudinal edgesof toggle plates 10 and 12 and the corresponding upward movement islimited by the buttons 14 which permit only a limited movement of theedges of toggle plates 10 and 12 between the heads of buttons 14.

A curved cover plate 15 is positioned above toggle plates 10 and 12.Cover plate 15 has its longitudinal edges return bent so that it may besprung over the longitudinal edges of spring plate 7 and beheld securelyin that position. Cover plate 15 is provided with a V-shaped slot in theupper end of half ring.

slots 16 and 17 to permit the movement therethrough of-half rings 11 and13 as the same are closed and opened. The upper end of half ring 11 isV-shape in form so that it may enter 13 when the two rings are broughttogether, half rings 11 and 13 being so positioned on toggle plates 10and 12 respectively that half ring 11 will register with opposing halfring 13.

The preferred form of my device, as perhaps may best be seen from Figure1, consists of a substantially rectangular shaped body 18 made of metalor fibre or other sulfi- -ciently stiff material. Body 18 is providedwith a plurality, in this case shown as five, of oval apertures 19 sopositioned that they will register with either half rings 11 or halfrings 13 when the body 18 is placed in posi tion in the binder. Cover 18is formed with an approximately V-shaped trough 20-positioned betweenapertures 19 and the edge of body 18. Trough 20 is so formed as toprovide a vertical ledge or stop 21 adjacent apertures 19 and in spacedrelation thereto. In

the distance between ledge 21 and the center of oval apertures 19.

When the parts are in the position shown in Figure 3 and cover 3 israised for the pur pose of closing the binder it will raise with it theouter ed e of body 18 which will cause the outer end of aperture 19 tocontact with half ring 13 and ride upwardly thereon, the inner end ofbody 18 moving outwardly alon the upper surface of cover plate 15 toguide body 18 in its upward movement. The notches 22 are provided sothat when the lower edge of bod 18 has moved outwardly to the inner sideof alf rings 13, half rings 13 will enter notches 22 to permit the lowerend of body 15 to continue to move outwardly, which will permit body 18to continue its upward movement'on half rings 13 without any binding ofapertures 19 on half ring 13.

When cover 4 is raised in a similar manner the body 18 will moveupwardly in the same way as the body 18 moved upwardly on cover 3 asjust described, and in doing so it will carry upward with it the sheets23 which are positioned on its u per surface. The relation of parts issuch that the inner longitudinal edges of sheets 23 will rest againstthe ledge 21 on body 18, and inasmuch as the distance, as justdescribed, between the inner longitudinal edges of sheets 23 and thecenters of apertures 24 is greater than the distance between ledge 21and the centers of apertures 19 the apertures 24 in sheets 23 will beheld in such a position that the outer edges of apertures 24 will be inspaced relation to the outer surfaces of half rings 11 and there will beno tendency for apertures 24 to bind on half rings 11.

In Figure 3 I have shown in heavy lines the binder in the open positionand in dotted lines the binder in the partially closed position.

In Figures 4, 6 and 8 I have shown modified forms of my device which aredesigned to function in a similar manner as the manner in which thedevice shown in Figure 1 functions, the difference being that I form myledge or stop in a different manner.

In Figure 4 I show a body 25 having oval apertures 26 similar toapertures 19 and having notches 27 similar to notches 22 but in thisembodiment of my invention I form the ledge or stop 28 by bending aportion of the edge of body 25 at right angles to such body and by thenbending the outside edge of body 25 into a plane parallel with the planein which the main portion of body 25 is disposed.

In Figure 6 I show a body 29 provided with oval apertures 30 similar toapertures 19 memes with oval apertures 36 similar to apertures 19 andhaving notches 37 similar to notches 22. In this embodiment a series ofstops 38 are formed by return bending onto the upper I, the size,

. ralityo surface of body 35 the material which was struck therefrom toform slots 37.

In Figure 10 I show a device similar to the device shown in Figure 4having a body 39, spaced apertures 40, slots 41 and a ledge or edge ofbody 39 which carries slots 41 is. curved downwardly towards the planein which the main body 39 is disposed so that the inner edge of mydevice will more quickly contact with'cover plate 15 when the covers '3and 4 of the book are raised.

It will be understood that the material from which my device isconstructed may be varied as desired and it will also be understood thatnumber and relative position of the oval apertures 19 and the notches 22and the similar apertures and notches shown in Figures 4, 6, 8, and 10,and also the height and relative position of the ledge or stop 20 andthe similar ledges or steps 28, 32, 38 and 42 may be varied as desiredto adapt my device to be used with difler'ent types of binders, -foraltho I have shown and described a specific structure and form of partas an exemplification of embodiments. of m invenplurality of spacednotches in alinement with the spacedapertures. Y

In witness whereof I have hereunto set my hand this 26th da ofSeptember, 1928.
